SImple question about sound waves but need a good reason

Click For Summary
High frequency sound waves do not travel faster than low frequency waves; the speed of sound is primarily determined by the medium through which it travels, not the frequency. While frequency and wavelength are inversely related, they do not directly influence the speed of sound in a given medium. The discussion highlights the distinction between phase velocity and group velocity, emphasizing that both concepts are important in understanding sound propagation. A physical explanation for the relationship between wavelength and speed is necessary to clarify misconceptions. Ultimately, the speed of sound remains constant in a uniform medium regardless of frequency.

Sound waves and frequency

Question:
Compare between the speed of high frequency (short wavelength) sounds to low frequency (long wavelength) sounds.
In my opinion, the answer is that frequency affects directly to the velocity of the sound.
Therefore, high frequency sound have high velocity.
Can someone post if this is right or not? If not, can anyone provide the correct answer? Thanks in advance.

It is non sequitur to say "the frequency directly affects the speed of sound therefore high frequency waves travel faster."

You will need to come up with a physical reason why the wavelength would affect the speed of sound. Also, does it make a difference whether you're talking about phase velocity as opposed to group velocity?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
